## Long description

The Rockforce RF-917G2 compression tester for diesel engines is a handheld diagnostic tool designed to measure cylinder pressure from 0 to 70 bar. Supplied as a complete kit with 19 threaded adapters, it connects to a range of injector and glow-plug ports to record peak compression values. The instrument is intended for workshop and field service use to assess cylinder sealing, valve seating, piston ring wear and overall engine health in diesel power units.
Advantages
The tester provides a wide measurement range suitable for most diesel engines and includes multiple adapters to fit various thread sizes and types. Its handheld design enables portable use during on-vehicle diagnostics or bench testing. The kit format reduces the need to source separate fittings and simplifies setup, while the clear pressure scale allows straightforward visual interpretation of peak compression.

How to use
Warm the engine to normal operating temperature, then disable the fuel system and ignition as required by the engine manufacturer. Remove the glow plug or injector from the cylinder to be tested and select the adapter that matches the port thread. Fit the adapter to the tester, screw it into the cylinder port until sealed, then crank the engine several revolutions while observing the pressure indicator. Record the peak pressure for comparison against manufacturer specifications or adjacent cylinders. Repeat for each cylinder and note any significant deviations or slow build-up of pressure.
Usage recommendations
Use the tester in accordance with vehicle service manuals and safety procedures. Ensure adapters are clean and threads are undamaged before use; apply appropriate thread sealing if specified by the adapter design. Avoid running the starter continuously—crank in short bursts to prevent starter or battery damage. Compare readings between cylinders and consult engine specifications to interpret results accurately.
